摘要：
Although there have been many studies on atomic layer deposition of Al2O3 to improve the electrochemical performances of ternary cathode materials, few studies considered the harsh conditions such as high temperature and high voltage at the same time. In this work, the Al2O3 passivation layer is employed to coat the high nickel (Ni) LiNi0.68Co0.10Mn0.22O2 cathode through atomic layer deposition (ALD) approach. The Al2O3 coated LiNi0.68Co0.10Mn0.22O2 presents superior cycling stability and rate capability than the pristine at the cut-off voltage...
